T O WHOM IT MAY CONCERN:

Bc it known 'that I, AZAMAH HUTCHINSON, of Monterey, Clermont county, Ohio, have invented a certain new and useful Fire-Proof Base for Stove Flues; and'I dohereby declare the following to be a full, clear, and exact description thereof, reference being had tothe accompanying drawings, making part of this specification.

The object of my invention is to secure houses from being burnt by the stove-pipe ilues which pass up' through thev ceilings or roofs of the chambers in which thel stoves arelocated, and I' provide against such accidents by insert-ing tho upper end of said stove pipes intera tube or cylinder, .which is surrounded with bricks or stones in such a manner as to render it fire-proof, and thus prevent the contiguous :joist o1" other wood-work taking fire from the heat of the stove pipe. In the accompanying drawings I l Figure 1 is a plan which shows the mode of attaching my fire-proof base to thejoists of a house; and Figure 2 is a vertical section showing the brick-work in position on-the base 'and a portion of the stove pipe inserted in the flue. The principal member of'my fire-proof base consists of a. bedplatet-A, which is pierced with a central and annular opening, B, and said bed-plate is suppliechwith a. number` of radialiV arms C C C C", D D D D, which arms D D D Dll have vertical continuations c e" ef ef terminating in flanges E E E VE, and these langes rest upon the joistsF F', and two trimmers G G', whose ends are mortised in saidjoists.4 H -is a cylinder or tube of cast iron, stone-ware, or other suitable material, and this cylinder is provided with a shoulder,A

h, by which means said cylinder is confined to a. central4 position within the annularfopcning B of the bed-plate. The lower end of this cylinder has a somewhat contracted portion, H', which projects through thc lathsfand plastering of the ceiling, and the upper e'nd of the stove pipe I is inserted in this portionof the eylirider. The cylinder H serves as a curb around which the brick-work-J is erected, and as will bescen by referring to iig. 2, this brick-work is supported upon the bed-plate A and radial arms C D. The chimney may be either circular or square in its horizontal section, as may be desired. When a square chimney is to be built themasonry can extend as far as the -arnis C D reach, but in erecting a circular chimney it need only rest upon the bed-plate A. It will be seen that a wall of masonry J and also a cylinder H, both of which arelgood non-conductors of heat, are interposed between the stovepipe and the wood-work, and as there is no open `iont where the pipe entersv the flue it will be an impossibility foran over-heated pipe to set iire to the building.i The cylinder H may extend as far u p within the chimney iiue as may bedesired. My 'lire-proof hase enables a chimney tu be built -at a greatly reduced cost, as it is only necessary to attach the arms tothe over-head joists, and run the masonry up through the roof of the building, thus saving the amount of bricks which would be necessary to carry the chimney up from the door of the room, and thereby economizing valuable space.

I claim herein as new, and of my invention` A {ire-proof base for stove ducs, consisting of' a bed-plate, Aahaving a central aperture, B, and radial arms C D E e, te., when used in connection with the cylinder H h H for the reception of'a stove pipe, tho whole beingr arranged and operating substantially as herein explained and for the Vpurpose set forth.

In testimony of which invention I hereunto set my hand.
